To all whom t may conce/ra.'

Be it known that we, @Hannes A. Mo- CARTY and 7M/DER A. JoNns, citizensof the United States, and residents of Plymouth, in the county ofPlymouth and State of Massachusetts, have inventedY a new and ImprovedVater-Heating System, o-f which the following is a full, clear, andexact description.

This invent-'ion relates to improvements inwater heating systems, andhas particular reference to such a system as used in connection` withwashing machines.

In large establishments, such as woolen mills where batteries ofwashingmachines are employed it has beenfound that the use of excessiveamounts of fuel,-. such. as coal, has been necessary in.f order tomaintain the water used inI the washing machines at proper temperatures.

It is proposed by the present i-nvention` to eii'ect an economy in fuelconsumption by the provision of an apparatusby means'of which thetemperature of col-d water isincreased previous to its entry into thewashing machines 4through the utilization of water discharged from saidmachines.`

Another object is to provide an apparatus of simple and inexpensiveconstruction and which is effective in carrying out thepurpose for whichit is designed.

The above and other objects willappear more clearly from the followingdetailed description, whentaken. inconnection with the accompanyingdrawings, which illustrate a preferred embodiment of the inventive idea.

In the drawings- Figure 1 is a diagrammatic viewshowing the applicationof the invention to a bat tery of washing machines, the tank' being insection; and

Figure 2 is a plan view of said tank.

Referring morev particularly to Figure 1, a pair of washing machinescomprising a battery are indicated by the numeral 5 and these machinesare supported in any suitable manner above the tank or vat 6- formingone of the essential features of thev present invention. A water heaterusually employed in connection with the washing machines 5 is alsoconventionally shown in Figure 1 and indicated by the numeral 7. Thisheater may be of any desired type, such as an instantaneous heater, andis utilized to increase Serial' N01.. 698,812.

the teirrperature of. the water previous to` its being fed into thewashing machines through the Amain feed. pipe 8 and the branch. feedpipes 9, each. ofthe latter pipes leading to one of said machines. Thewater to' be supplied to the machines 5 may be taken from any suitablesource and is pumped to saidfmachines by means of a suitable pump 10,.also conventionally shown in Figure 1. Should it be desired;y to supplycold water direct-ly tothe machines 5 this may be done through the vpipe1'1 which.` is connected by branches 12. to. said machines, the flow ofwater through; said pipe 11 being controlled by a gate valve 13insaidpipe. However, should it be desired to heat` the water before enteringthe machines the Valve 131 is kept closed` so: that the cold water fromthe source of supply willnot enter'the pipel1,but flow downwardly intothe inlet pipe 14which projects into the tankv 6 to al point adjacentthe bottom thereof. l Associated with the inlet pipe 14- is an outletpipe 15 and connecting these twovpi-pes arel series of coils 1'6` eachincluding a pair of pipes having ad `jacent ends connected to the pipes14 and 15 and their opposite ends connected by a union 17 ,said coilscombining to formy a primaryA heating 'unit designed to increase; thetemperature of the water iowingfrom the `source of. supply beforeentering the heater 7. The iiow of water through the inlet pipe 14 iscontrolled by agate valve1`8 which is opened. lwhen it is desired toheat thel water and which is kept closed when cold water is feddirectly. tothe machines through the pipe 11..

The tank. 6, which is. formed of` concreteV or any other desir-ablematerial, is provided at one end with spaced partitions 19' and 20, theformer' of which extends from thev openy top of the tank toa pointadjacent the bot.- toml thereof, while the latter partition which` isinterposed between the partition 1.9 and one end of the tank extends;from the bottomy to. a poi-nt near the top, `the height of saidpartition 2O determining the water level*` inthe tankl when the same issupplied with the heated water discharge fromh the machines 5,as'will-,bepresently described. The water in the tank 6 which overflowsthe partition 20 is carried away through a-suitable drain 21. Should itbe desired to completely empty the tanka gate valve 22 is employedpumped into the system by the pump 10` before it reaches the heatingelement 7 the valves 27.

vopposite end of each pipe 25 is positioned over the tank adjacent theend thereof opposite the partition 20. A normally closed gate valve 26in each of the pipes 25 controls the flow of water from the machines 5to the drain outlet 21 while similar valves 27 control said flow fromthe machines into the body of the tank. Should it be desired to increasethe temperature of the water used water in the machines 5, which hasbeen previously heated to the proper temperature, may be discharged fromthe machines 5 into the tank 6 by opening the This water rises to thelevel of the top of the partition 2O and in so doing the coils 16 areimmersed therein and heated by said water so that as the water from theinlet pipe 14 passes throughY the coils its rtempe'rature is increasedmaterially before it enters the inlet pipe 15 from whence it flows tothe heater 7. Here the water is raised to the desired temperature andthen fed through the pipe S and branch pipes 9 to the machines 5. In theevent that it is desired to discharge the water from the machines 5, asat the completion of the operation thereof, without permitting saidWater v to flowv into the tank 6 the valves 2G are `opened ytherebypermitting the water from the machines to flow through the drain 21.lVhat is claimed is.: y 1. The combination with a washing ma chine and aheating element connected with the, machine for supplying heated Waterthereto; of a tank above which said machine is supported and into whichthe water in the machine is directly discharged, a heating .coil insaidtank for raising the temi; E'perature vof water fed to said coilfrom a source of supply, and a connection between said coil and heatingelement for feeding the water to the latter subsequent to its pas` sagethrough said coil.

2. The combination with a washing ma chine and a heating elementconnected with the machine for supplying heated water thereto; of a tankabove which said machine is supported, a heating coil inV said tank forraising the temperature of wate fed to said coil from a source ofsupply, a connection between said coil and heating element for feedingthe water to the latter subsequent to its passage through said coil, andmeans for permittinof the heated water from said machine to bedischarged directly into said tank to heat the coil therein.

3. The combination with a washing machine and a heating element forsupplying heated water thereto: of a tank having a drain outlet, aheating coil in said tank for raising the temperature of water fed tosaid coil from a source of supply, a connection between said coil andheating element for feedine water to the llatter subsequent to itspassage'through said coil, means for permitting the flow of heated waterfrom said machine directly to said tank to heat the coil therein,` andmeans for discharging water from saidmachine directly through said drainoutlet without affecting said coil.

4. The combination With a Washing machine and a heating elementforvsupplying heated water thereto; of a tank having a partition thereinforming a compartment in the tank and providing anl overflow for thetank below the level of the topr thereof, a drain outlet on one side ofsaid partition, water feeding means on the opposite side kthereofconnected to a suitable source of supply and also to said heatingelement, means for dischargingheated water from said machine into saidtank to immerse said feeding means whereby the temperature of the waterpassing therethrough is increased prior'to its entry into said heatingelement, and means also permitting the discharge of water from saidmachine into said tank and through said drain outlet without affectingsaid feeding'means.

5.. The combination with a Washing ma- `chine and a heating element forsupplying heated water thereto; ofa tank having a vpartition thereinproviding an overflow for the tank below the level of the top thereof, adrain outlet on one side ofsaid partition, water feeding means on theopposite side thereof connected to a suitable source of supply and alsoto said heating element, means for discharging heated water from saidvmachine into said tank to immerse said feedingmeans whereby thetemperature of the water passing therethrough is increased prior to itsentry into said heating element, means also permitting the discharge vofwater from said machine/into said tank and through said drain outletwithout affecting said, feeding means, and a valve associated with saidpartition for permitting the tank to be Ven'iptied through said drainoutlet.
